- Abstract
- PSP resins form a unique class of heat resistant resins which are now developed on an industrial scale by SMPE. They are obtained by a condensation reaction between aromatic dialdehydes and methylpyridines. They are viscous or semi-solid oligomers, soluble in usual solvent, hot salt processable, and can be cured between 200 and 150 deg. C. Their main characteristics is a high heat resistance and easy processability. Their ability to five rise to composite materials with good mechanical behavior especially at high temperatures (250 deg. C and above) is used in some of their applications: graphite and glass reinforced structural parts, glass reinforced plastic radomes for use up to 450 deg. C, fire resistant protections, and many high temperature applications.
